What this means →
Why this one spills

The problem here is local, not the works.

This overflow spilled 64 times on days its own treatment works stayed shut — so the works still had capacity. That points upstream, to this branch of the network, rather than to a works too small for its catchment.

How this verdict is reached →

Can its works cope?

Full capacity view →

This overflow drains to Buckfastleigh STW, serving about 7,795 people.

of permitted flow
Not assessed

The works has headroom — so spills here point to another problem, often on that branch of the network (a blockage, a failed pump or infiltration).

The same works has emergency overflows too

All emergency overflows →

4 pumping-station emergency overflows feed Buckfastleigh STW works — raw-sewage relief outlets that should fire only when a pump fails. They are not in this page's feed; between them they have discharged about 2,054 recorded hours.

What you can do about this one

OPEN NOW

Ask for the data

Under the Environmental Information Regulations, Stonepark Crescent, Ashburton's telemetry, the works' flow-to-full-treatment setting, and any spill investigations are emissions information — they cannot be withheld on commercial-confidentiality grounds. A written request is the fastest lever.

BY 30 APR 2027

Get it into the next programme

Investigations that will shape the 2030–35 environment programme must complete by this date. Putting this overflow on the record now — to South West Water and the Environment Agency — is what gets it considered.

BY 1 NOV 2027

Put it in the drainage plan

South West Water's draft Drainage & Wastewater Management Plan goes to a twelve-week consultation. A named overflow with evidence behind it is far harder to leave out.
